The cheapest way is to add a system with NTOP running on it, on a system spanned to the external interface. I use a dual NIC Linux Snort sensor that also runs NTOP from www.ntop.org
Its canned graphs will give you a ten-minute usage, a one hour usage, a one day usage (sampled each 30 minutes) and I think the last one is a month.
